We developed a method based on ARMS-PCR to genotype Zucker rats and quickly differentiate the mutated fa allele from the wildtype. This method is reliable for setting up and maintaining breeding colonies in animal facilities and assigning animals to control and treatment groups based on their genotypes in animal studies.
Due to the genetic mutation (fa) in the gene encoding for leptin receptor, homozygous Zucker rats (fa-/-) develop excessive adiposity and become an experimental animal model in obesity and metabolic-related diseases research. Based on tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR), we developed a method to quickly genotype Zucker rats with a mutated fa allele from their wildtype littermates. The three genotypes are clearly discriminated on 2.0% agarose gel. Our method can be used as a reliable tool to set up and maintain the breeding colony in animal facilities as well as assign animals to control and treatment groups based on their genotypes for animal studies.
